Cable Tray - Fire-Resistance

1) It is a structure of metal shell, double fire-resistance covers and inorganic trunk.

2) It has a very good inner supporting construction to fix inorganic trunk effectively.

3) The average thickness of lagging is 25mm.

4) Usually the double covers could be used for ventilation and thermolysis, and fire retardant coating sprayed inner side. When it comes across fire, the coating would expand and block the ventilation holes, then the cables become safe.

5) The inorganic trunk passed the 60 minutes refractory experiments tested in National Fixed Refractory Experiments Center.
